通過ID或名稱的聯盟查詢

您好，我正在嘗試開發一個看似簡單的報告，其中有人可以輸入ID號或名稱並搜索和檢索數據。只有當我擁有所有的標準時，我才能使其發揮作用，並且我嘗試了幾種不同的方式。 First，Last和ID中的每一個都是填充或留空的框。這裏沒有浪費太多空間是我基本上做的，任何人都可以幫忙嗎？通過ID或名稱的聯盟查詢

聯盟：

Select 
worker_id as "ID", 
worker_last_name as "Last", 
worker_first_name as "First", 
worker_phone_home as "Home_Phone", 
worker_email as "Email" 
from worker 
where worker_id = :parm_EB_pnum --inputvalue 
UNION 
Select 
worker_id as "ID", 
worker_last_name as "Last", 
worker_first_name as "First", 
worker_phone_home as "Home_Phone", 
worker_email as "Email" 
from worker 
where (
upper(worker_first_name) like upper(:parm_EB_first) and 
upper(worker_last_name) like upper(:parm_EB_last) 
)

這是我使用=，而不是像類似的結果也試過，我需要兩個輸入。我試圖在沒有UNION的where子句中使用CASE語句，但得到了相同的結果

我不知道，我在這裏看到的問題。查詢是否返回你想要的內容？如果沒有，發佈一個可重複的測試用例。發佈DDL來創建'worker'表，DML插入一些示例行，告訴我們綁定變量是什麼，並告訴我們你想要返回哪些行。 –

它只會返回行，如果我填入ID，first_name和Last_name。我希望它只在輸入ID或名字和姓氏時才返回值，而不是全部。對不起，我不清楚 –

是這些值中的一些值爲空嗎？這可能會導致問題。 – Hogan

當您使用like時，應該使用%。此外，與orwhere條件將足以爲您正在嘗試做什麼。您也可以執行trim以刪除輸入值中的任何空格。

select 
worker_id as "ID", 
worker_last_name as "Last", 
worker_first_name as "First", 
worker_phone_home as "Home_Phone", 
worker_email as "Email" 
from worker 
where worker_id = :parm_EB_pnum 
or upper(worker_first_name) like '%'||upper(:parm_EB_first)||'%' 
or upper(worker_last_name) like '%'||upper(:parm_EB_last)||'%'

有沒有辦法讓這個工作不需要所有的值？我想知道它的軟件（argos）。當我有ID，名字和姓氏時，它似乎只給我結果。它很好，但很可能人們只會使用其中一個或另一個，ID或名稱 –

或在查詢中做到這一點。當滿足3個條件中的任何一個時，返回一行 –

嘗試

Select 
worker_id as "ID", 
worker_last_name as "Last", 
worker_first_name as "First", 
worker_phone_home as "Home_Phone", 
worker_email as "Email" 
from worker 
where worker_id = (CASE WHEN :parm_EB_pnum > 0 THEN :parm_EB_pnum END) 
UNION 
Select 
worker_id as "ID", 
worker_last_name as "Last", 
worker_first_name as "First", 
worker_phone_home as "Home_Phone", 
worker_email as "Email" 
from worker 
where 
upper(worker_first_name) like (CASE WHEN :parm_EB_first IS NOT NULL THEN upper(:parm_EB_first) END) 
and upper(worker_last_name) like (CASE WHEN :parm_EB_last IS NOT NULL THEN upper(:parm_EB_last) END)
